L/70 : A 40mm AA gun

9K35 "Strela 10": (NATO : SA-13 Gopher)

One Air Defence Brigade is attached to a Command/Corps/Division depending on the need.

AD Brigades themselves consist of Air Defence Regiments.

While a AD Brigade is sort of permanently attached to a parent Command/Corps/Div formation, the AD Regiments will keep rotating.
The AD Regiments will hold the actual equipment metioned in above tweet.
Different types of AD regiments exist .

Just remember

AD = Air Defence

Regt = Regiment

SP = Self Propelled i.e. Wheeled/Tracked unit

Comp = Composite i.e. combination of 2 different systems
The most basic AD Regt will contain either
23mm ZU-23-2 AAA gun OR 40 mm L/70 AAA gun

"23" denotes the projectile caliber and "2" denotes the twin barrels.

ZSU-23-2 can also be mounted on a truck. Then it's called a SP regiment.

ZSU-23-4 "Shilka" SPAAG is basically a four barreled 23mm AAA on a tracked platform. It has a small radar for target tracking.

SPAAG = Self Propelled Anti Aircraft Gun

#IndianArmy #AirDefenceCorps had probably acquired 48 or 96 such Shilka SPAAGs.
BEL recently upgraded 48 Schilka systems. The first was upgraded in 2014 and last in 2020.

@KesariDhwaj IIRC each AD Regiment has 24 guns.
So 96/24 gives us four regiments of ZSU-23-4 Schilka with some guns for training

From the stamps issued by Army, I could find 4 such Schilka regiments as they have Schilkas in their pics.
@KesariDhwaj @Editor_Orbat

140 AD Regt (SP)
142 AD Regt (SP)
144 AD Regt (SP)
151 AD Regt (SP) (CHHAMB)

(for noobs : Chhamb is a battle honor of the regiment )
